     item() -> number

     Returns the value of this tensor as a standard Python number. This only works
     for tensors with one element. For other cases, see :meth:`~Tensor.tolist`.

     This operation is not differentiable.

     Example::

         >>> x = torch.tensor([1.0])
         >>> x.item()
         1.0
